  1. 3. An area in the mantle where heat rises as a thermal plum. High heat and lower pressure at the base of the tectonic plate cause melting of the rock – into magma. This magma rises through cracks and erupts to form volcanoes.
  2. 5. Hot molten rock (mixed with gases and mineral crystals)
  3. 7. A natural feature of the Earth’s surface.
  4. 9. The interior region of the Earth between the core and the crust.
  5. 12. Plate A type of lithospheric plate that forms the continents. Is thick and made of less-dense granite.
  6. 14. Boundary Where two tectonic plates move away from each other causing magma to rise and c
  7. 15. Compass directions on a map (N E S W)
  8. 16. The visible features of an area of land, made up of landforms.
  9. 17. The study of the physical features of the Earth’s surface and what caused them.
  10. 18. Boundary Where two tectonic plates move towards each other and collide.
  11. 21. Plates Also called tectonic plates.
  12. 22. Boundary When two tectonic plates slide horizontally past each other.
  13. 24. Zone The location where the sinking of a convergent boundary takes place.
Down
  1. 1. Hazard Naturally occurring phenomena like tsunami’s, volcanoes and earthquakes.
  2. 2. Arc A chain of oceanic islands volcanoes occurring at the overriding tectonic plate of a subduction zone. Bounded by a deep oceanic trench and formed by magma that rises from the melting of the descending plate.
  3. 4. Refers to when one lithospheric plate sinks under another.
  4. 6. Crust The top layer of the oceanic portion of a tectonic plate.
  5. 7. The solid, outer part of Earth made up of the crust and upper mantle.
  6. 8. The study and drawing of maps.
  7. 10. Part of the Earth’s mantle lying beneath the lithosphere and made of denser semi-solid rock. Extends from about 100 km to 700 km below the surface.
  8. 11. Any of the world’s main continuous expanses of land.
  9. 13. Convention The symbols used on maps.
  10. 19. Plate A large, irregularly shaped slab of lithosphere that moves like a raft over the Asthenosphere.
  11. 20. The branch of science dealing with Earthquakes and land movement.
  12. 23. An unusually large ocean wave.
